Why pineapple is the symbol of hospitality?

The pineapple made its way to America through importing methods from the Caribbean in the seventeen hundreds. Since it is rare and has unique characteristics, it was soon the symbol for hospitality in early America. But the problem was getting the pineapple to other places because the only trade routes were by ship. When the ship arrived it was considered to be a great achievement to arrive with a pineapple.
Another story tells that New England ship captains would return from their journeys and would put a pineapple around peoples houses as a symbol of a safe return. The pineapple has such a unique style to it that it was often used as the centerpiece in food banquets. It was also used as for decorating for arriving guests through 18th and 19th centuries. The pineapple still remains the symbol of hospitality today. It just has that warm welcoming sense to it that says you are welcome to come in.
I believe the story when families had dinner they would place the pineapple in the center of the table and invite neighbors to come eat with them. When the neighbors would walk in and they would see the pineapple in the center of the table and it just became that sense of hospitality to them. The other story is when New England sea captains came back and put pineapples around everyone's houses. This would then create that sense of safety and security for hospitality to be based around. The other story is also related to this story too. It says that when it was imported to America it was such a hard journey just to get the pineapple to the destination that when it did arrive it was outstanding that it did.
